What is the electric field outside a charged spherical shell?
Outside a charged spherical shell, the electric field behaves as if all the charge is concentrated at the center of the shell. This is known as Gauss's Law for a spherical surface, which states that the electric field at a distance r from the center of a charged spherical shell is equivalent to that of a point charge with the same total charge as the shell at the center. Therefore, the electric field outside a charged spherical shell decreases with the square of the distance from the center of the shell.
How can you calculate the total charge on a spherical body if its radius R and surface charge density sigma are given?
Uh, assuming by "spherical body" you mean "spherical shell of insignificant thickness" then it would just be 4*pi*(R^2)*sigma
Mentoin two special properties for uniformly charged spherical shell?
A uniformly charged spherical shell will have a constant electric field inside the shell and zero electric field in the hollow region. Additionally, the electric potential on the surface of the shell is constant and only dependent on the total charge and radius of the shell.
What is the formula for the surface area of a rhomboid?
what is the formula to finding the total surface area of a rhomboid?!
How do you calculate total surface area for aveoli in lungs?
The total surface area of alveoli in the lungs can be estimated using the formula for the surface area of a sphere, as alveoli are roughly spherical in shape. The average diameter of an alveolus is about 0.2 mm, leading to an approximate radius of 0.1 mm (0.0001 m). Given that there are around 300 million alveoli in the lungs, the total surface area can be calculated using the formula ( A = 4\pi r^2 ) for one alveolus, and then multiplying by the total number of alveoli. This results in a total surface area of approximately 70 square meters, providing a large area for gas exchange.
What does the s stand for in the formula for the surface area of a cone?
it stands for the total surface area
What is the formula to calculate the total surface area of a cube?
Total Surface Area = 6L2. Where L = the length of one side of the cube.
What is the Formula total surface area of a cube?
Total Surface Area of Cube is 6a2 . Here "a" is the "length of each side" of the cube.
How does the surface area change when a large cell gets smaller but has the same total volume?
The surface must get more spherical. When it reaches a perfect sphere the surface area cannot be reduced without also reducing the volume.
What is the surface charge density formula of a sphere?
The surface charge density formula of a sphere is Q / 4r, where is the surface charge density, Q is the total charge on the sphere, and r is the radius of the sphere.
What is the formula for finding the total surface area of a cone?
Total surface area in square units = (pi*radius*slant length)+(pi*radius squared)
The total number of electrons inan electron shell is reepresented by the formula 2n . is this correc?
The maximum number of electrons in a shell / energy level is given by 2n2.
